STITCHLESS )EIOOK TAPE Application filed. February 23, 1927. Serial No. 170,244.

My invention relates to stitohless, rivetless put'with agiven number of machines and hook or eye tapes in which the hooks or employees. 7 eyes are inserted into the tape fabric with In the drawing I have shown my invenout sewing or riveting and in which the pull tion applied to a hook tape but I do not or strain comes against a fold in the fabric limit myself to the precise form shown.

The eye tape embodying my invention is the Subject matter of a separate application for patentand my invention resides essentially in folding a piece of fabric to form a multi-ply tape With the Wire forming the hooks or eyes passing though the plies to lock them into position so that all sewing or riveting is eliminated.

I claim l I l. Stitchless hook tape comprising a strip of fabric folded to form a face ply, a return ply on the back of the face ply, a third ply extending over the free edge of the return play then outwardly to form a fourth ply and inwardly again to form a fifth ply and a hook member passing through all of said plies with its bill exposed on the face ply and its base loops lying in the fold between the third and fourth plies.

2. Stitchless hook tape comprising a strip of fabric folded to form a face ply, a return ply on the back of the face ply, a third ply extendingover the free edge of the return play then outwardly to form a fourth .ply and inwardly again to form a fifth ply and a hook member passing through all of said plies with its bill exposed on the face 3 ply and the base loops lying between the third and fourth plies, the shank of the hook being exposed on the back of the tape. Stitchless hook or eye tape comprising a strip of Woven fabric folded on itself into a plurality of plies the tape edges overlying the middle portion of the folded tape. fasteners of the hook and eye type passing through said plies and edge portions With their operative portions exposed on the face of the folded tape at a distance from the edges thereof and their bases lying Within said folds, the fasteners themselves serving to unite the various plies of fabric. 7
